Answer 1

Краткая запись:

Всего-150 м.

Первая бригада- 4500 кг ? мешков

Вторая бригада- 3000 кг ? мешков

Решение:

1) 4 500+3 000=7 500(кг)-собрали всего

2) 7 500: 150=50(кг)- в одном мешке

3) 4 500: 50=90(м)- первая бригада

4) 3 000: 50=60(м)- вторая бригада

Ответ:

Первая бригада собрала 90 мешков, вторая бригада собрала 60 мешков.

Answer 2

Problem Analysis

We are given that two brigades collected 150 identical sacks of potatoes. One brigade collected 4,500 kg of potatoes, while the other brigade collected 3,000 kg of potatoes. We need to determine how many sacks of potatoes each brigade collected.

Solution

Let's assume that the first brigade collected x sacks of potatoes. Since the second brigade collected 150 sacks in total, the second brigade must have collected 150 - x sacks of potatoes.

We know that the weight of the potatoes collected by the first brigade is 4,500 kg. Since each sack of potatoes is identical, we can calculate the weight of each sack by dividing the total weight by the number of sacks: 4,500 kg / x sacks.

Similarly, the weight of the potatoes collected by the second brigade is 3,000 kg. We can calculate the weight of each sack by dividing the total weight by the number of sacks: 3,000 kg / (150 - x) sacks.

Now we can set up an equation to solve for x:

4,500 kg / x sacks = 3,000 kg / (150 - x) sacks

To solve this equation, we can cross-multiply:

4,500 kg * (150 - x) sacks = 3,000 kg * x sacks

Simplifying further:

675,000 kg - 4,500 kg * x sacks = 3,000 kg * x sacks

Bringing all the terms involving x to one side:

7,500 kg * x sacks = 675,000 kg

Dividing both sides by 7,500 kg:

x sacks = 675,000 kg / 7,500 kg

Simplifying:

x sacks = 90

Therefore, the first brigade collected 90 sacks of potatoes, and the second brigade collected 150 - 90 = 60 sacks of potatoes.

Answer

The first brigade collected 90 sacks of potatoes, while the second brigade collected 60 sacks of potatoes.

Note: The above solution assumes that the weight of each sack of potatoes is the same.
